Welcome to Golden Steel Material Let’s Talk
Q & T 700 Plates are ultra-high-strength structural steels that have been heat-treated through a precise Quenching and Tempering process to achieve a minimum yield strength of 700 MPa. This specialized thermal cycle involves heating the steel to an austenitic phase followed by rapid cooling (quenching) to create a hard martensitic structure, which is then reheated (tempered) to restore toughness and ductility. The result is a material that is nearly three times stronger than conventional S235 structural steel, enabling the construction of high-performance components that can withstand extreme mechanical loads.
Designed for weight-critical engineering, Quenched and Tempered 700 steel allows for a significant reduction in plate thickness without compromising structural integrity. This high strength-to-weight ratio is essential for the mobile machinery industry, where reducing dead weight directly translates to increased payload capacity and improved fuel efficiency. With excellent cold-forming properties and superior weldability for its strength class, Q & T 700 is the industry standard for telescopic crane booms, heavy-duty trailer chassis, mining equipment, and bridge components operating in demanding environments.
